Red Hat Security Advisory: Red Hat OpenStack Platform 16.1.4 (etcd) security update

Notes

Topic

An update for etcd is now available for Red Hat OpenStack Platform 16.1 (Train). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details

A highly-available key value store for shared configuration. Security Fix(es): * large slice causes panic in decodeRecord method (CVE-2020-15106) * DoS in wal/wal.go (CVE-2020-15112) * directories created via os.MkdirAll are not checked for permissions (CVE-2020-15113) * gateway can include itself as an endpoint resulting in resource exhaustion and leads to DoS (CVE-2020-15114) * improper validation of passwords allow an attacker to guess or brute-force user's passwords (CVE-2020-15115) * no authentication is performed against endpoints provided in the --endpoints flag (CVE-2020-15136) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
